LAMP.

SPECIFICATION forming part of Letters Patent No. 674,317, dated May 14,1901.

Application iiled August 22, 1900. Serial No. 27,745. (No model.)

To all whom t may concern:

Be it known that I, BoMoNJEE DORABJEE PUDUMJEE, residing at Gharni road,Bombay, India, have invented a new and useful Lamp, named The TriplexLamp, for Carriages, Cycles, and other Vehicles, which lamp is fully setforth in the following specification, reference being had to theaccompanying drawings. Y

My invention is in the nature of a triplex lamp or lantern which can beused with an oil-light alone or with` such light combined with either anacetylene-lighter a candlelight, or the acetylene-light or candle-lightcan be used alone; and the invention consists in certainnovelconstructions and combinations of parts, as will be described andclaimed.

In the drawings, Figure 1 is a front elevation of my lamp or lantern.-Fig.-2 is a front view, and Fig. 3 a side view, of theV oil-can. Fig. 4.is a detail View of the burner-tip. Fig. 5 is a detail view of the gauzedisk. Fig. 6 is a detail longitudinal section of the tube. Fig. 7 showsa modiied form of safety-valve. Fig. 8 is a detail view of thefollower-disk. Fig. 9 is a side view of the lamp or lantern. Fig. 10shows a different form of ventilator. Fig. 11 is a detail View showingthe burnertip applied to the filling-cap of the water-reservoir. Fig. 12is a detail View illustrating the slide for closing the match-opening,and Fig. 13 is a detail partial cross-sectional view of the bottom ofthe lamp-body.

The principal parts of the lamp are,- rst, the box or main body A of thelamp, which is provided with a chimney or ventilator like A in Fig. 1 orA2 in Fig. 10; second, an oilcan B, with a burner; third, a cylindicalreceptacle C, for holding a candle or calcium carbid; fourth, awater-reservoir D at the back of the lamp, and, fifth, a lamp-holder E,attached to the back of the water-reservoir.

This lamp may be made of brass, copper, aluminium, steel, or any othermetal.

The box or main body A of the lamp in which the flame is produced andfrom which light radiates consists of three vertical sides and a top anda bottom. It has a broad front tapering into a narrow back. To the frontis hinged a glass cover a, which can be opened and shut. The box A isconstructed with a tapering body, with a view to obtaining as wide arange ofillunlination as possible. The

jthree vertical sides of the box have polished 'surfaces for reiectinglight or can be tted with ordinary removable reliectors. of the box A isfitted with a chimney or ven- The top ered with a slide of redglass F',to admit of a match to ignite the lamp. The box or main body contains anoil-can B, `fitted with a burner. 4The oil-can has a gap or round recessin the front, corresponding with an opening in the bottom of the box,through which holding a wax candle orcalcium carbid. This receptacle isheld in its position by a flange C', fixed outside to the bottom of thebox, to which the receptacle can be screwed on or off.

The oil-can is tted with a semicircular burner containing a Hat wick,which can be raised or lowered by means of a horizontal shaft B', havinga button at the end which projects out through one of the vertical sidesof the lamp. The burner of the oil-can has its place toward 'the back ofthe box, the oilcan having a higher elevation at the back than at thefront. The sides of the oil-can slope from the top to the bottom, so asnot to block the draft caused by the perforations in the sides of thebox, and the oil-can is raised from the bottom of the box by a ridge B2with the same object, One of the vertical sides of the box is slotted tot the horizontal shaft B of the burner to allow of the withdrawal of theoil-can from the body of the lamp. The slot is covered with a groovedslide B3. The oil-can has an opening at the top which is covered with ascrew-stopper B4, through which opening the oil-can can be filled withoil.

The cylindrical receptacle C is suitable for holding calcium carbid or aWax candle. It contains a spring C2 to push the candle up as it getsconsumed. The spring is tted with a round perforated follower-plate O3for greater safety against explosion when calcium carbid .is inserted acylindrical receptacle OA for.

is used in the receptacle and for supporting the candle when the latteris used as an illuminant. The receptacle C has a removable nipple or tipCAL at the top, `which can be screwed on air-tight by means of a thinrubber washer. rlhe nipple O4 has a li ne aperture facing a circularpiece of wire-gauze f2, fitted in the inside of the nipple. The nippleprojects out into the box through the flange C at the bottoni of thebox. The receptacle is provided with an air-tight cap C at the bottom ofthe recegtacle,which can be screwed off and on when necessary. When acandle is to be burned in the receptacle, the nipple Ol should beremoved to allow the wick of the candle to burn. Then screw off the capC6, insert the candle through the bottom, push the spring in behind thecandle, and screw on the cap Cn tightly. The cap contains a rubberwasher to make it air-tight. When calcium carbid is required to be usedinstead of a candle, replace the nipple and fill about two-thirds of thereceptacle with calcium carbid, with the spring C2 remaining in thereceptacle, and then screw tight the cap C6. The receptacle is providedwith a safety-valve G, Fig. 6, or G', Fig. 7, which opens under abnormalpressure of gas. The safety-valve may be like one shown in Fig. 6 orlike that shown in Fig. 7. Sufficient quantity of water is allowed torun into the receptacle C through a rubber tube H, shown in Fig. 9,connecting the receptacle C with the waterreservoir D. The rubber tubewill serve also as an additional valve. Should the safetyvalve ever failaccidentally to work, it is possible the rubber tube may get blown offunder very high pressure of gas. The water-reservoir is provided with atap D, to which one of the ends of the rubber tube His attached. The tapcontrols the flow of water into the receptacle. The reservoir is filledwith water through an opening at the top, which is covered by aremovable screw-stopper D2, with an aperture in the center. When thenipple C4 of the receptacle C is required to be pnt aside when a candleis to be burned in the receptacle, the nipple may be screwed onto thestopper DE, as shown in Fig. ll.

To the back of the water-reservoir a lampholder E, Fig. E), is fixed forattaching the lam p to a carriage, cycle, or other vehicle. lt consistsof two springs N and O and a screwclamp consisting of plate X and screwY. The springs absorb jolts, and thus prevent them from beingcommunicated to the lamp. The clamp is adjustable and can be fastened toany ordinary lamp-bracket by means of the plate X.

The advantages of this lamp may be described categorically as follows:First, it is capable of burning oil; second, it is capable of burningwax candles; third, it is capable of burning acetylene gas; fourth, ithas a novel shape 4so designed as to throw bright light over a widerange in front of the lamp; fifth, it can be taken to pieces forcleaning purposes, and, sixth, it can give simultaneously twolights-wiz., oil and acetylene or oil and candle.

'lhe utility of the lamp consists in its capability of being usedaccording to the fancy, convenience, or immediate requirements of theuser. It is simple in construction and easy of manipulation. It doesaway with the necessity of keeping three separate lamps for the threecombustibles-viz., oil, acetylene gas, and wax candles-it beingthreefold in character, and hence commendable for cheapness andportability.

Having thus described my invention, what I claim, and desire to secureby Letters Patent, is-
